To all whom it may concern:

Be it known that We, WILLIAM W. Benson and HARLEY L. CLARKE, citizens of the United States, residing, said Bonson, in the city of Dubuque, in the county of Dubuqueand State of Iowa, and said GLARKE, in the city of Chicago, county of Cook, and State'of Illinois, have invented certain new and use ful Improvements in lvlatch-Starters for EX- plosiveEngines, of which the following is a specification.

Our invention relates to match starters for gasolene engines and our object is to provide a combined match starter and priming cup that can be fitted on to any gas, gasolene or other internal combustion engine in such. a manner that the charge in the combustion chamber ofthe engine may be ignited forthe first time in starting'an engine, Without the use of the battery or electric sparker usual for securing the initial explosion in this type of engine The manner in which we accomplish the ends songhtwill; be i'ully describedand shown in the following specification, when read in connection with the drawings accompanying the same and forming a part hereof, in which- Figure l is a perspective View of .our device. Fig. 2 is a vertical section through the line A-A of Fig. 1. Fig. 3 is a cross section through line B-B of Fig. 2. Fig. 4 is a cross section through line DD of Fig. 1. 5 Like charactersof reference denote corresponding parts in-each of the drawings. Referring to the drawings, 2 designates a spindle provided with screw threads 4 at the top and a shoulder 5 near the bottom where it is widened out into a valveof truncated cone shape 6 having a roughened or threaded surface 8. Through the spindle is drilled 'an orifice or hole l0.- The threads t on the top of the spindle are engaged by corre- 5 whereby the cup is rigidly held on the 5 indie and said cup 12 is provided with an 011 hamber 14 having a removable cap or cover 15 the side 0d the cup'ds a stop co k 16 provided with a handle 18. An ifi g0 ggtends from, oil chamber 14 through the body of the cup and throughthe sto ock 16 and registers with the orisponding-threads on a metal oil cup 12.

1 lies 10 in the spindle, whereby it is adapted to take the oil from the oil cup 1% and (leliver it into the combustion chamber of the engine below the match hereinafter to be described.

The match starter member 22 is composed oi a hollow body providedwith a shoulder 25 onthe outside and the upper end formed into a neck 26. The hole or opening that extendsthrough the member 22 is, in its upper part, ofthe size of the body of the spindle 2 but permits said spindle to move 1 therein. Thelower end of the member 22 is recessed at 28 forming an opening or chamber-considerably larger than the openin in the upper part of the member and this chamber opens out at its bottom into the cylinder or ex'fplosion chamber of the engine. The upper portion of the metal surrounding the recess 28 is ground and forms an air tight valve seat- 29 for the truncated cone shaped valve 6. Around the "22 is coiled a spring SO' Which engages at one endthe shoulder 25 of the member 22 and at the other end the lower end 32 of the 7 holding the match in a given position there .isprovided an opening in said member 22 I, at nearly right angles to the hole 35 which opening is screw threadedand in it is screwed a thumb screw having a handle 42, or an ordinary stop cock may be used and operated by 'a lever. The lower end of the member 22- is screw threaded; and adapted to be screwed into the casing of the englue and opens into the combustionchamber. The mode of assembling and operating our device is substantially as follows: The spindie 2 is inserted upward through the member 22 till the shoulder 5- engeges the shoulder or valve seat 29 in the inner side of the recess 28. Then the spring-'30 is coiled-around the spindle and the member 32 and the cup 12 is screwed on to the screw threads 4 of the spindle 2 somewhat compressing the spring 30. The device, as new assembled, is then screwed into the cylinder or the compresently to appear, in which is adapted to be inserted a match 8'6 For the purpose of 7 5 spindle/ 2 and theupperlpart ofthe member bustion chamber of the-engine'with the re;-

cess 28 opening out nto the combustion chamber-of the en ine. The chamber 14; of the oilcup 12 is led with oil and a match 36 is inserted in the hole 35 and forced forward into the chamber 28' and the set screw "40 tightened against the match withthe 1 grasps the handle 18 of the stopcock 16 and igniting end of the' match contact with the'roughened or threaded surface 8 of the truncated cone valve 6. The operator then turns the cock until it registers with the orifice 'in the cup 12 and the oil runsdown through the hole '10 through the-spindle into the chamber 28 below the end of th match a and then into the combustionchamber of combustion chamber of the engine. 20

the engine. If gas be used as the fuel, then the gas isturned .oninto therecess 28 or I After suflicient oil .has been supplied to the recess 28, the stop cock 16 is closed, thus preventing the escape ofany gases through the hole 10.

The engine is then brought in the right tion and the operator strikes a sharp upon the cover 15 of the cup 12, which forces the spindle downward against the spring 30, and brings the roughened surface 8 into engagement with the igniting end of the match 'and'this match explodes the charge inside of the'combustion chamber of the engine.

Immediately, upon the hand being removedfrom the cover 15, the spring 30 comes into 'taction and reseats the valve 6 upon the ,I valve seat 29 of the member 22 and prevents the escape of all of the gas from the chamber 28. from the opening and, the opening is closed by the set screw 40, thus preventing all of the escape of gases through the orifice 35. If for any reason the match should not be ignited, all'that is necessary to be done is 4 to simply remove the match and put in another one and strike again upon the-cover. 15 oftheoilcup. U v

Itwill be observed that it is simple 1n construction, is durable, is easilyoperated,

requires no special shape or size match, prevents'the escape of all gases, can be attached to any make of en inc, the oil being delivered through the orifice 10 below the end of the match there is no chance of'the match becoming wet whereby it would miss fire or prevent the ex losion in the chamber The burned match 36 is then withdrawn member in which a match is held, an oil cup' secured to the member and having fluid connection with the combustion chamber of the engine, and means operated by the oil cup adapted to engage the ignition end of the match and fire the same to explode the charge in the engine;
